| Know before using | A foundational library, not yet an exhaustive stitch encyclopedia. | The interface and plan description do not prove tester reach, completion, feedback quality, fit validity, export quality, uptime, support, or suitability for an established release process. Measurements and photos can be sensitive personal data. Run a non-critical pilot, review the current privacy and service terms, define consent and photo rights, test exports and deletion, and keep pattern approval and release responsibility with the designer. | The result is a numerical unit conversion, not a new measurement or conformance decision; it does not establish sample or lot representativeness, significant digits, drape, warmth, opacity, thickness, stretch, strength, shrinkage, durability, sewability, end use, target, or tolerance. | A factory profile, platform label, bid, estimate, or message does not establish current identity, factory ownership, capability, capacity, workmanship, pricing, compliance, delivery, or project fit. Paid-plan visibility can affect who responds. Verify the production site, subcontracting, references, samples, quality and compliance records, specifications, commercial terms, and remedies directly. |

| What the source establishes | The linked tool or guide is maintained inside Stitch Authority and was checked against its current public interface. | Pattern Testers currently offers application intake, tester selection, feedback, photos, approvals, issue tracking, revisions, a reusable tester directory, and release deadlines. The public pricing page shows a limited free plan and paid Pro and Business tiers. Its June 2026 privacy policy lists names, email addresses, measurements, photos, feedback, application history, and assignments among the data processed. | The calculator uses the NIST SP 811 Appendix B.8 conversion from avoirdupois ounces per square yard to kilograms per square metre and links to a source-reviewed fabric mass record for method, sampling, conditioning, and product controls. | Maker's Row currently lets a brand submit a project before advance sign-up, then provides access to an account. Its project workflow records product details and files and connects projects with factories by location and specialty. Search guidance lists apparel capabilities such as pattern making, sourcing, sample making, and production. Factory access to bids is plan-dependent. |
